Revealing mistakes: When the ATM is dragged behind the car, the white sparks can be clearly seen coming from inside it and not from the bottom as from the friction with the asphalt road.
Factual errors: When the home video at the start of the film catches a glimpse of the initial bomb blast, we see the flash and hear the boom at the same instant. Anything close enough to a nuclear blast to hear the boom at the same instant as seeing the flash would be instantly disintegrated.
Continuity: When Walter Mung throws the check back at Zora, it lands on the floor. As she leaves the truck, the check has somehow been placed on the counter (right side of the screen).
Continuity: In the scene when they are stealing the ATM the tires on the SUV change from both spinning, to only the right one spinning, and then back to both spinning.
Factual errors: The Electro-Magnetic Pulse from the nuke would have wiped the camcorder.
